The Taklamakan and Gobi Desert (TGD) region has experienced a pronounced increase in summer precipitation, including high-impact extreme events, over recent decades. Despite identifying large-scale circulation changes as a key driver of the wetting trend, understanding the relative contributions of internal variability and external forcings remains limited. Researchers, including School of Earth and Atmospheric Sciences Professor Yi Dengapproached this problem by using a hierarchy of numerical simulations, complemented by diverse statistical analysis tools. The results offer strong evidence that the atmospheric internal variations primarily drive this observed trend. Specifically, recent changes in the North Atlantic Oscillation have redirected the storm track, leading to increased extratropical storms entering TGD and subsequently more precipitation. A clustering analysis further demonstrates that these linkages predominantly operate at the synoptic scale, with larger contributions from large precipitation events.

Control of electrical doping is indispensable in any semiconductor device, and both efficient hole and electron doping are required for many devices. In organic semiconductors, however, electron doping has been essentially more problematic compared to hole doping because in general organic semiconductors have low electron affinities and require dopants with low ionization potentials that are often air-sensitive. In a recent study, a team of researchers, including Stephen Barlow of the School of Chemistry and Biochemistry and the Center for Organic Photonics and Electronics, adapted an efficient molecular doping method, so-called ion-exchange doping, to dope electrons in a polymeric semiconductor.

Weather forecasters talk about wind shear a lot during hurricane season, but what exactly is it?  School of Earth and Atmospheric Sciences Senior Academic Professional Zachary Handlos teaches meteorology in a part of the country that pays close attention to the Atlantic hurricane season. In this article, Handlos provides a quick look at wind shear, one of the key forces that can determine whether a storm will become a destructive hurricane.
